Module: Prism::DSL

Defined in:

lib/prism/dsl.rb

Overview

The DSL module provides a set of methods that can be used to create prism nodes in a more concise manner. For example, instead of writing:

source = Prism::Source.new("[1]")

Prism::ArrayNode.new(
  [
    Prism::IntegerNode.new(
      Prism::IntegerBaseFlags::DECIMAL,
      Prism::Location.new(source, 1, 1),
    )
  ],
  Prism::Location.new(source, 0, 1),
  Prism::Location.new(source, 2, 1)
)

you could instead write:

source = Prism::Source.new("[1]")

ArrayNode(
  IntegerNode(Prism::IntegerBaseFlags::DECIMAL, Location(source, 1, 1))),
  Location(source, 0, 1),
  Location(source, 2, 1)
)

This is mostly helpful in the context of writing tests, but can also be used to generate trees programmatically.
